Good time of the day.
Zgemma H10 COMBO is a fairly simple device that works smartly.
You just have to get used to the terminology. Multiboot Android + Enigma2 is called image.
I liked the OpenPLi 8.1 variant, where TV programs look elegant with rich content. At the same time, I have not yet figured out where Android is located, but I know that Lunix is the basis. In principle, this does not matter to me, 4 options for installing the image are provided, it works quite reliably, almost not killed, if only a hardware malfunction. The following scheme is carried out. Immediately after turning on the power, press and hold the "OK" button. The receiver's display will show boot, then rCUY and you can release the button. The multiboot menu from points 1-4 will be displayed on the monitor screen. There, the image is loaded from the media. If there is a connection to the Internet via LAN, then the choice of image options is made directly from the portal. For this model, the Zgemma H10 images are suitable, but for some reason there is no native one.
There was a case that I tried to install an image from Zgemma H9 COMBO, after editing the table of contents of the image. Got a brick. The firmware process is simple. Unpacked the ZIP file of the image to a USB drive. Connected the drive (FAT32) to the USB port on the rear panel. Turned on the receiver while holding the reset button. As soon as the receiver's display logo begins to flash, release the reset button. We are waiting, in case of a successful image, the receiver will reboot on its own after the firmware process is completed.
